Part Number:

225-9022A

Cold storage required. Shipping restrictions may apply.

Limited Shelf Life

Overview

Coated Filters, Filter, ISO-CHEK®, 1 PTFE and 1 glass fiber filter coated with 9-(N-methylaminomethyl) anthracene (MAMA), preloaded in a 37-mm two-stage cassette that provides separation and collection of the vapor and particulate phases of isocyanates; requires Cat. No. 225-9050 Note: Does not include Derivatizing Solution, which is required for use with the ISO-CHEK® Sampling System. See Cat. No. 225-9023 or 225-9023A for ISO-CHEK Cassettes with Derivatizing Solution included.

Details

ISO-CHEK is the only filter-based sampling system that simultaneously traps and separates both monomers and oligomers at the point of collection for highly sensitive physical and chemical characterizations of diisocyanates including HDI, MDI, IPDI, HMDI, 2,4-TDI, and 2,6-TDI. The IRSST-developed ISO-CHEK offers rapid 15-minute sampling, stable samples, and a 40% reduction in sample preparation and analysis time compared to other methods. ISO-CHEK meets ASTM D5932-96 and D6561-00 specifications.
